Denbigh Asylum Killings

When local teenagers discover a body at the disused Denbigh Asylum, it seems that his murder might be linked to a modern slavery ring trafficking young people from the Indian subcontinent. However, social media then reveals that the victim was involved in a toxic relationship which may provide a clue to his death. When there is another murder, the focus of the investigation switches again. With time running out, Ruth and the Llancastell CID team must find the killer before they flee the country and disappear.
